Scientific Linux Security Update : rpm on SL7.x x86_64 (20141209)

critical Nessus Plugin ID 80016

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was found that RPM wrote file contents to the target installation directory under a temporary name, and verified its cryptographic signature only after the temporary file has been written completely.
Under certain conditions, the system interprets the unverified temporary file contents and extracts commands from it. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation.
(CVE-2013-6435)

It was found that RPM could encounter an integer overflow, leading to a stack-based buffer overflow, while parsing a crafted CPIO header in the payload section of an RPM file. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation. (CVE-2014-8118)

All running applications linked against the RPM library must be restarted for this update to take effect.

Solution

Update the affected packages.
